i don't think i've ever woke up from a dream laughing
are you conscious of the fact your dreaming when you're dreaming?
i've been in dream situations were i know i'm dreaming, or at least sleeping
one time in particular, reading a sign was crucial to completeing a task in the dream, but i couldn't focus on the words, i remember thinking if i would only open my eyes i'd be able to read the sign, and at the same time reasoning that if i opened my eyes i'd wake up and the dream would be gone, in the end i woke up feeling tired and rather frustrated
